Firefly

Never played Traveller, but watching Firefly, I got a very strong Alternity vibe.

Oddly enough, when playing Alternity (Star*Drive), I got a very strong Traveller vibe.

Yeah, when I saw Firefly I immediately thought of Traveller. However, IMHO the Traveller T20 rules for starship combat are kind of clunky. I figured that Firefly would be pretty easy to run using GURPS Space or Traveller.
